SPECIFICATION forming part of Letters Patent No. 739,871, dated September 29, 1903.

Application filed May 23, 1903. Serial No. 158,415. (No model- 'To all whom it may concern:

Be it known that I, WARREN S. HILL, a citizen of the United States, residing at Hydepark, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Window Attachments, of which the following is a specification.

My invention relates to attachments for windows, and more particularly to metallic casings therefor. 1 w A It consists in the various features hereinafter described and more particularlyclaimed.

In the accompanying drawings,"Figure 1 is a perspective view of a portion of a window having two sashes to which one embodiment of my invention is applied, together with its frame, parts being broken away. Fig. 2 is an enlarged horizontal section taken in a plane at the meeting-rails of the sashes. Figs. 3 and 4: are perspective views of a portion of the inner and outer casing-strips,-respectively. Figs. 5 and 6 are similar views of reinforcing-strips for the above and for the intermediate casing-strips, respectively. Fig. 7 is a broken horizontal section through a window having a single sash to which another form of my invention is applied, and Fig. 8 i]? a'partial vertical section'on the line 8 8 of Similar characters indicate like parts throughout the several figures of the drawings.

In devices of this class difficulty has been encountered in securing a casing-strip which shall give a surface of contact with the sash resulting in free movement and at the same time freedom from rattling and complete ex-' clusion of dust and which While having considerable resiliency to allow these results to be efiected will be sufficiently strong that it will not break in use. i As a consequence metallic window-casingshave been little used in practice. My invention overcomes such difficulties by the construction'which'will now be described.

The numerals 10 and 11 designate, respectively, the lower 'and upper sashes of a window movable in a frame 12'between the inner cleat 13 and the outer projection 14. The sashes are more directly supported by my improved attachment, which is arranged as folover their bases.

lows: Each sash is preferably provided with pairs of opposite grooves 1515, extending verticallyalong the inner and outer faces near each edge and having their inner walls preferably curved, substantially as illustrated. With the inside groove of the lower sash c0- acts the casing-strip A. As here shown, this consistsof a strip of thin sheet metal forming at one part a base member 16, then bent substantially at right angles to furnish a stem 17, then in a cylindrical head 18, extending in the opposite direction from the base, to furnish a member of double thickness, into engagement with the sash-groove, and, finally, back parallel to the stem and base. Since to secure the requisite flexibility the material of which the casing is formed'is quite thin, the base may be reinforced by a member 18, also of sheet metal, bent over both sides of said base and, if desired, soldered or otherwise secured thereto. Openings 19 through the base and reinforcement, preferably elongated to permit lateral adjustment, receive screws 20.130 secure the strip beneath the cleat 13, there being sufficient space between the edge of the cleat and the stem to allow some play of the strip.

"The casing member between the two sashes may conveniently consist of a double strip B, formed of two strips A A, similar to A, but having their bases and contact-beads extend ing in the same direction. These separate strips may be secured together to form a unitary member by a reinforcing-strip 21, common to both, extending beneath and bent The stems of the strips A may 'be separated by any desired distance sufficient, for example, to occupy the same space as the ordinary form of parting-bead, and thus provide for ready application of the device to old windows. To close the space between the stems and prevent the passage of outer air through the channel thus formed, a filling member'is provided, preferably consisting of an elastic block'22, of rubber or other suitable material, situated at the meeting-rails of the sashes and extending from them to the frame. Each block may be secured in place by a nail 23 driven through it into the frame or in any other convenient manner. Such a filling member serves not only-as a closure, but also permits the springstrips to yield toward one another, as is desirable in this form of casing.

The groove in the outside of the upper sash is engaged by a casing-strip O, conveniently formed in the same general manner as one of the elements A of the strip B, except that instead of the material extending from the bead parallel to the opposite side to form the double stem and base it projects at 24 at an angle to the stem, forming a guard, forced by the resiliency of the material with some pressure against the projection 14 and preventing access of air and dust. The reinforcingstrip may be applied in a manner precisely similar to that of the strip A, except that it here surrounds but a single thickness of the material. The openings 19 may be arranged the same in all parts of the casing. It will be understood that, as is usual in devices of this class, the sash contacts only with the strips at the sides and not with other portions of the frame.

Figs. 7 and 8 show the attachment applied to single-sash windowssuch as are in use, for example, upon railroad-cars. Here, of course, the intermediate strip 13 is omitted and the sash 25 is supported between the strips A and C, engaging grooves in the inner and outer sides, respectively, they being formed and operating in the manner above described. In this connection or in any other it may be found expedient to reinforce the curved bead 18 to prevent its being dented or crushed. As here illustrated, this is effected by inserting within the head a wire 26, which may be soldered in place.

In both applications of the device the sashgrooves preferably have a circular lateral contour or are of such form that the cylindrical bead of the casing may rock or rotate freely therein under the influence of any spring in the stem. This prevents strain from being brought upon the casing by the play of the sash.

With windows in some situations, as upon cars, particularly exposed to the ingress of dust, it may be found convenient to apply a guard-strip where the sash meets the sill. For this purpose one of the hereinbefore-described attachments maybe used, being situated within a recess in one of the elements the stem holds the strip closely in contact to guard the opening throughout its entire length.

It will be seen that my improved attachment provides smooth continuous surfaces of contact with the sash without projecting angles, which assures easy movement of the latter and freedom from cutting in or altering the shape of the groove, and that this surface of contact is relatively large and effective in excluding dust. Further, while the closed or continuous form of the contact-bead is such as to give the maximum strength and the base amply rigid to keep it in true alinement this is obtained without sacrificing the elasticity of the spring-stem, which maintains the pressure of the strip against the sash and prevents rattling and the leakage of air and dust. The efficiency of the device in this latter respect is greatly enhanced by the spring-contact of the outer strip with the edge of the.

frame.

Having thus described my invention, I claim 1. The combination with a window-sash and its frame, of a casing for said sash consisting of inner and outer strips secured to the frame, each strip comprisinga base, a stem projecting therefrom and a contact-bead for coaction with the sash carried by the stem, and the outer strip also having a spring member contacting with a portion of the frame.

The combination with a window-saslr and its frame, of a casing for said sash consisting of inner and outer strips secured to the frame, each strip'comprising a base, a stem projecting therefrom and a contact-bead for coaction with the sash carried by the stem, the inner strip having said stem and base of double thickness, and the outer strip having a spring member contacting with a portion of the frame.

4. The combination with a window-sash and its frame, of a casing for said sash consisting of inner and outer metallic strips secured to the frame, each strip furnishing a base and stem projecting therefrom, then bent to form a curved bead and then extending inwardly along the stem, the inner strip having this inward extension parallel to said stem.

5. The combination with a window-sash and its frame, of a casing for said sash consisting of inner and outer metallic strips secured to the frame, each strip furnishing a base and stem projecting therefrom, then bent to form a curved bead and then extending inwardly along the stem, the outer strip having this inward extension projecting at an angle from said stem.
